for all of the folks that are wondering why they have no sound here is the procedure .Onthe 05 ram with the infinity system there is a amp mounted behind the glove box you must unplug this amp and take it out you almost have to remove it to get the plugs out you can remove glove box by opening the box then pressing in on both sides at the rear of the box. box will dropout behind box there will be a plate made of plastic this plate extenends tothe other side of the dash remove enough screws so this plate will swing out but not off this will allow you to get to the amp there are 3 bolts hold theamp in place 2 you can see and 1 that is on the left side you can not see these are 10mm get that bolt on the left out is astruggle be careful of very sharp metal edge! when you get the amp out our just unplug it if you can your almost home free .now you need to track down a amp bypass plug made by metra part #70-6510 some retailers will tell you you need a#70-6512 do not listen to them if you amp has 2 plugs you need the #70-6510 the guys at metra will tell you the same thing the plug is 49.95 it plugs right in you get both plugs plus a head unit plug with just your hot and ground and constant on and illumination leads the amp plugs come with about 10ft of wire if you want to wire in another amp. when you do this procedure you willloose your 3 dash speakers you can get them back if you wire in a after market amp . wire up the head unit as you would of normally white to white white/black to white/black and so on this will give you the two front door speakers and the two rear door speakers there will be alot of wires left over these are for your centers in the dash you must run them to a aftermarket amp .or you can do what i did and forget about them because there factory crap any way and you cant get to them to replace them so ijust replaced my door speakers with polks and the sound is great no amp needed .to remove door panels front doors have 4 screw remove door handle is a10mm bolt remove and handle comes off with it lift door panel up and it will seperate from door unhook leads and now you can replace those crap factory speakers. hope this helps some one.
